Pentanchidae (Deepwater catsharks)
Etymology: Cephalurus: cephalus, from kephale (Gr.), head, referring to its expanded, flattened and rounded head; ailouros (Gr.), cat, probably an allusion to the vernacular “catshark,” so named for its cat-like eyes. (See ETYFish); cephalus: From kephale (Gr.), head, allusion not explained, probably referring to its expanded, flattened and rounded head, “much wider” and with larger pores compared with the similar Parmaturus xaniurus, its presumed congener at the time. (See ETYFish).

Found on the upper continental slope and outermost shelf. The expanded branchial region of this shark suggests that they are adapted to bottom areas with low dissolved oxygen levels. With little information available, reproductive mode could either be ovoviviparous (Ref. 244, 53776) or oviparous, paired eggs are laid (Ref. 50449).
Life cycle and mating behavior

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Other sources describe ovoviviparity as an alternative reproductive mode (Ref. 244, 53776).
